What we deliver in Mortlake.
Each Mortlake street has its own typical layout — Victorian terrace, Edwardian semi, 1930s detached. We adapt the recommendation to the house, the planning context and how you actually want to live.
Side-return and rear extensions turn Mortlake's narrow Victorian kitchens into open-plan family rooms. We design and build them in-house, handling planning where needed.
Loft conversions add a master bedroom and en-suite to Mortlake's terraces — extra space without losing the garden.
New-build plots are scarce in Mortlake, but we take on replacement dwellings and infill where they arise.
SERVICE 01 House extensions in Mortlake
A house extension is the biggest investment you can make in your home — it should transform how your family lives, not just add square metres. We design every extension around how you actually use your space, with a fixed, itemised price and stage-based payments so you stay in control from first sketch to handover.

SERVICE 02 Loft conversions in Mortlake
A loft conversion adds an entire floor without losing any garden. We design lofts as proper rooms — full-height ceilings, generous windows, en-suite bathrooms — not afterthoughts squeezed into the rafters.
